Sony NR - Help Understanding

I enjoy taking pictures, but have never gotten into the finer points of IQ. As I began researching cameras to buy a new one, I have come across a few discussions that I am not clear on, one of which is NR in Sony cameras.

People in the forum have said Sony uses too much noise reduction. What does this mean exactly? In another thread someone posted 2 pics (I believe the HX5 vs LX3), comparing the NR. To me there wasn't a noticeable difference. What exactly should I be looking for?

I mainly print 4x6 prints, and don't enlarge, so would this even be an issue?

Firstly, NR is an abbreviation for "noise reduction." NR is not generally invisible in small 4" X 6" prints taken at ISO settings of ISO 400 or less. However, some folks who want to enlarge HX5 photos, taken at ISO settings above ISO 400, to 11" X 14" or 16" X20" will see some fine detail blurring in the image. NR is only apparent in prints greater than 8" X 10" taken a high ISO settings.
